FlexSPINSPI configurable multi-motor driver with micro-stepping from STMicroelectronics

FlexSPIN allows to power and control multi-motor systems, managing simultaneously stepper and DC motors, and providing a unique level of integration in term of control, power and additional features.

Through the serial peripheral interface bus (SPI), plenty of features can be configured, such as 3 voltage regulators, 1 high precision A/D converter, 2 operational amplifiers and 14 configurable GPIOS.

The possibility to drive simultaneously stepper and DC motors makes FlexSPIN the ideal solution for all the applications featuring multi-motors.
